CC Adi-lila

It should be noted that a gṛhastha (householder) must not make his livelihood by begging from anyone. Every householder of the higher castes should engage himself in his own occupational duty as a brāhmaṇa, kṣatriya or vaiśya, but he should not engage in the service of others, for this is the duty of a śūdra.

CC Adi 10.50, Translation and Purport:

Śrīla Murāri Gupta never accepted charity from friends, nor did he accept money from anyone. He practiced as a physician and maintained his family with his earnings.

It should be noted that a gṛhastha (householder) must not make his livelihood by begging from anyone. Every householder of the higher castes should engage himself in his own occupational duty as a brāhmaṇa, kṣatriya or vaiśya, but he should not engage in the service of others, for this is the duty of a śūdra. One should simply accept whatever he earns by his own profession. The engagements of a brāhmaṇa are yajana, yājana, paṭhana, pāṭhana, dāna and pratigraha. A brāhmaṇa should be a worshiper of Viṣṇu, and he should also instruct others how to worship Him. A kṣatriya can become a landholder and earn his livelihood by levying taxes or collecting rent from tenants. A vaiśya can accept agriculture or general trade as an occupational duty. Since Murāri Gupta was born in a physician's family (vaidya-vaṁśa), he practiced as a physician, and with whatever income he earned he maintained his family. As stated in Śrīmad-Bhāgavatam, everyone should try to satisfy the Supreme Personality of Godhead through the execution of his occupational duty. That is the perfection of life. This system is called daivī-varṇāśrama. Murāri Gupta was an ideal gṛhastha, for he was a great devotee of Lord Rāmacandra and Caitanya Mahāprabhu. By practicing as a physician he maintained his family and at the same time satisfied Lord Caitanya to the best of his ability. This is the ideal of householder life.
